Application filed August 16, 1926.

This invention relates to new and useful iu'iprovements in rail anchors,and the object of the'invention is to provide a simple and eflicientdevice which will prevent longitudinal movement or creepage oi' the.rails under traflic.

Another object is to provide a rail anchor which may be veryeasilyattached to the rail to hold same in place.

A further object is to provide means on the anchor to efficiently gripthe sides of the base or flange of a rail and to contact with the tiesto resist the stresses set up in the rail by the passage of traflicthereover.

A still further object is to provide an anticreeping device forpermanent ways which will be economical in use and very easilymanufactured.

In my invention I provide rail anchor having a main. body portion withupwardly turned hooks or jaws at each end, one oi said jaws beingadapted to overlie one edge of a rail flange while the other jaw orhooked projection extends above the level of the rail flange on theother side thereof. Extending outwardly from the main body o'ilgtheanchor and at an angle oi approximately 85 thereto is the strut or tiecontracting portion through which the forces, caused by traffic on therail or by expansion or contraction, are transmitted between the railand the tie. Thehooked projections of the main body portion are providedwith recesses into which are placed inserts having teeth adapted to outinto the rail flange to hold the rail in position. These inserts ortoothed portions are preferably made of hardened steel and are insertedinto the mould in which the body of the anchor is cast. The insertsbeing cast with the body are immovable in the recesses and the teeth aretempered or chilled so that they will cut into the rail flange whendriven into rail engaging position.

In the drawings which illustrate one form of my invention;

Figure 1 is a plan view of my improved rail anchor.

Figure 2 is a side elevation of the device shown in Figure 1.

Figure 3 is an end elevation of the rail anchor shown in Figures 1 and2.

Referring more particularly to the drawings, 11 designates the main bodyportion ot the anchor which extends from side to Serial No. 129 ,592.

side of the flange 12 of the rail 18. Formed integral with and on oneside of the main body portion is the upwardly turned hooked projectionor jaw lat whichis adapted to overlie or embrace part of the edge of therail flange. Formed integral with and on the other side of the main bodyportion is the upwardly turned hooked projection or jaw 15, the inneredge 16 of which is made in the form of an arc to allow easymanipulation of the device when attaching it to the rail. Reccsses 17are formed in the jaws and in said recesses are cast the inserts 18, theedges 19 of which contact with the edges of the rail flange. The edges19, which are made in the form of an are are serrated or are providedwith teeth 20 which, when driven against the ail, cut into same and terman eiflcient means for locking the anchor in position. The inserts orthe toothed portions of same are preferably made of a metal harder thanthe rail, so that they will cut into the flanges. The recesses arepreferably made as shown, that is of dovetailed cross section so thatthe inserts are locked in the anchor. Projecting outwardly from the side21 of the anchor and cast or formed integral therewith is the tiecontacting portion or strut 22, the main web 22) of which is preferablydisposed at an angle of approximately 85- to the surface 21 as shown, sothat when the anchor is driven into position the web 23 will lieparallel to the rail and transmit the forces which occur between therail, and the tie, in a direct line parallel to the longitudinal axis ofthe rail.

The face 2-1 01 the strut 22 is made in the form of an arc to facilitatesecuring the anchor to the rail base with the strut contacting with thetie. The strut may be reinforced by the ribs 25 to strengthen it. In thedrawing, the main body portion of the anchor is made of channel shapedcross section suitably ribbed to strengthen same, but this may bemodified without departing from the spirit oi the invention. Parts 26and 27 ot the main body portion near the hooked projections or jaws maybe formed to contact with the bottom 28 ot' the rail and the part 26 maybe provided with an extension 26 to form a guide and a steadying meanswhen driving the anchor into position.

In operation, the anchor is placed on the under side of the bottom ofthe rail with one hooked projection or jaw overlying one or the flangesand with the strut engaging with the adjacent tie. lhe other jaw portionextends above the rail flange on the side of the rail remote from thestrut. The anchor is supported manually and is then driven into positionby light hammer blows delivered on the side of the anchor remote fromthe strut and the tie with which it contacts. The anchor at this pointin the operation of attaching it to the rail has its side angularlydisposed to the side of the tie. The light blows force the said end ofthe anchor towards the tie and the tendency for the anchor to springback or away from the tie forces the teeth against the edges of the railflange so that they out thereinto and look the anchor in position, litwill be readily seen that a device constructed in this manner may beeasily nmnu'hictured and easily applied to rails to prevent creeping ofsame through any of the well known causes. It will, also, he seen thatonce the device is secured to the rail there is very little danger ofthe anchor becoming loose through vibration of the rails as the tendencyof the teeth under loosening movement is to bite into the rail and forma. good grip thereon. The device once applied needs very littleattention and is, therefore. very economical in use when com mrcd withthe rail anchors usually employed.

Having thus described my invention, what I claim is 1. A rail anchorcomprising a single castng extending in the transverse direction of .herail. and contacting with the base thereof, said casting having upwardlyproject ing portions, one of which is grooved so that its uppermost edgeoverlies the rail. base, metallic inserts fitting snugly into recessesformed in the projections and surrounded by metal comprising same, sothat there is no relative movement between them, said inserts havingteeth which contact with each side of the rail flange and bite into sameto hold the anchor in position.

2. A rail anchor comprising a single cast ing adapted to extendtransversly of the rail and provided with an upwardly projecting portionat each end, extending above the rail flange, one of said projectionsbeing grooved to allow part of same to overlie the rail flange anddovetailed recesses in said projections adapted to receive and hold inposition inserts, the edges of which, adja cent the rail flange, areserrated to bite into the rail when driven thereon.

A r-ail anchor comprising a single casting adapted to embrace the edgeof the rail on one side and project above said flange on the other side,and metallic inserts of harder material than said rail cast into saidanchor and surrounded by the cast metal formin the main body of theanchor, said inserts iaving the surfaces contacting with the rail curvedin the form of an arc and provided with toothed projections which cutinto the rail flange to hold the anchor in position.

4-. A rail anchor comprising a single cast ing extending from side toside of a rail and provided with upwardly projecting portions, one ofwhich is adapted to embrace the edge of the rail base, while the otheris adapted to extend above said base and is curved in the form of anarc, metallic inserts fitting into dovetailed recesses in saidprojections, said inserts having toothed projections adapted to cut intothe flanges of the rail, and means projecting outwardly from one side ofthe anchor to contact with a railroad tie adjacent the point. where theanchor is secured.

In witness whereof, I have hereunto set my hand.
